TO ALL WIIOM IT MAY CONOERN:

Be it knownl that I, SAMUEL RUE, Jr., of the county of Chester, andState ofPennsylvania, have invented a. new and useful Improvement in theGilford Injector; and I do hereby declare that the following is a fulland exact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon.

The nature of my invention'consists in the construction of the Giffordinjector with a closed partition between the receiving-chamber ofthesteam-delivery nozzle and the reeeiving-ehamberof the water-deliverynozzle, whereby' I dispense with the steam-packing, and the vulvesincidental to other modes of construction,

'thus giving great simplicity tothe apparatus, so that it may bemanufaeturedat a greatly-reduced price, and

not liable to get out of order, as will be seen by the followingdescription. In the accompanying drawings, which -ma-he a part of thisspecification- Figure 1 is an isometrical view of the improved injector.

Figure 2 is a vertical longitudinelpsection of the same.

Like letters in both figures indicate the seme parts. t

A is the steam-receiving chamber, which has an elbow, a, to which thesteam-pipe is connected, and esteeml nozzle, B, which projects throughthe Water-receiving chamber C into the water-nozzle D, on the front endofthe said chamber. The receiving-water pipe is connected to the elbow 6ofthe chamber C. The steam-receiving chamber A is represented in thedrawings as confined to the water-receiving chamber C, by means ofscrew-bolts c. The construction may, however, be varied withoutdeviuting from the principle embraced in the combination. E is anadjustable plug, to which the water-nozzle D is connected; and F is asmiling-box ofthe saule. G is the stuing-hox of the discharge-pipe II,which extends into the fitting, on the outer end of which a screw is cutto receive the watebsupply pipe. J is the everiow-chambei, and K thedisehargepipe of the seme. L is a forked lever foi` operating the plug;EandM, arod jointed thereto, the seid rod being extended to thecngineroom, to be under the control ofthe engineer. l

It will be seen that the flew ot'v water is regulated by the adjustmentof the water-plug E so ns to vary the area between the erternalperiphery of the steam-nozzle B and the interna-l periphery of thewater-nozzle I).

What I claim as my invention, and desire to secure by Letters Patent,is-

The construction and arrangement of the receiving-chamber Awith itsnozzle B, the water-receiving chamber C, and adjustable plug E,substantially as hereinbefore described.

In testimony whereof, I have hereunto set my hand and affixed my seal,this 12th day of December, 1867.
